The centerpiece of the award-winning, revolutionary design of the Atomic Aquatics Frameless Dive Mask, is an optical quality, distortion-free, UltraClear lens. Focused on fit, comfort and a wide vision field, the close fitting skirt, and the single large lens, work in harmony to reduce volume and minimize hydrodynamics. Tucked behind the lens, the Squeeze-to-adjust buckles are nearly invisible to oncoming water flow. In Clear or Black soft silicone rubber, and two fit sizes, this may be your perfect dive mask.
